an atom
A quark is the smallest particle in matter.
The particle theory is called the "particle model" or "particle theory of matter." It proposes that all matter is composed of tiny particles that are in constant motion.
The smallest particle of matter is called an atom. It is the basic unit of a chemical element and retains the properties of that element.
A piece of matter moving through space is called an object or a particle.
The hypothetical particle called the Higgs boson is also known as the "god particle", pressumably because of its important role.

An atom A fundamental particle
The measure of energy of motion of a particle of matter is called kinetic energy. It is calculated using the formula KE = 0.5 * mass * velocity^2, where mass is the mass of the particle and velocity is its speed.
A substance that is composed of only one kind of matter is called an element. The smallest particle of an element is called an atom.
